17.30 . CP A 25 000-kg subway train initially traveling at
15.5 m>s slows to a stop in a station and then stays there long
enough for its brakes to cool. The station’s dimensions are 65.0 m
long by 20.0 m wide by 12.0 m high. Assuming all the work done
by the brakes in stopping the train is transferred as heat uniformly
to all the air in the station by how much does the air temperature
in the station rise? Take the density of the air to be 1.20 kg>m3 and
its specific heat to be 1020 J >kg # K.

Thank you for visiting my website! I post videos by, what I consider to be, the best YouTuber's as well as my own original lessons. My main goal is to teach students better problems solving skills for advanced math and physics. If you are interested in private lessons, please contact me via WyzAnt.com/Tutors/JJtheTutor

Amazing, Life Changing Tutor
Before I met Jonathan, I was struggling through most of my STEM classes because I was simply not studying properly. He taught me all kinds of new study habits that would help me to save time, raise my grades, and lower my stress. Jonathan was specifically tutoring me in vector calculus and is an amazing tutor on the subject. You will walk away from a lesson with a game plan knowing exactly what you need to do before your next session with him or before your next exam in order to do well in the course. I highly recommend him as a tutor.
